The Ratina shopping centre is Tampere’s largest retail and recreational centre. Ratina employs hundreds of people and houses more than 150 shops, restaurants, and other businesses. Ratina is a tour de force of steel structures’ design and our largest construction-management project to date. Steel structures for exceptionally challenging applications were used for the three buildings that form the complex. The structural engineering project was a result of our expertise in renovation engineering, bridge and special-structure design, and industrial and element engineering.
